OK, clarification on something please. Is this essentially XS, or
something more primitive?
More primitive. This is for "I have an external library that I need
to wrap" code. The sort of thing people use XS' prototypes and such
for. If you need to write parrot-accessing code in C, you'll use a
higher-level mechanism.

Oh JITters... ;^)
Yep. You'll note the #define check in nci.c. :)
